stm32F446re usb cdc virtual com port not showing up as the usbd_desc.c
Hey everyone, I'm learning about USB CDC and soon USB HID. I think I successfully program the stm32 as a cdc device because I can connect to it, and I can read and write serial commands through a terminal. I can even catch the serial buffer through t...
Resolved! STM32 H5 I3C CCC transmit
I used STM32H563 transmit a message through I3C CCC direct.I create a new CCC command "0xA0".Control send the command to target.But target will enter HAL_I3C_ER_IRQHandlerUesd the general command "0x89".The target can receive this command. The Buffer...
STM32U5A5: SAI1 as PDM MIC interface
Does anybody have an example code how to use SAI in STM32U5A5 as PDM interface?I use STM32U5A5, with LQFP64 package. So, I understand from datasheet: the SAI (I have just SAI1 available om pins), supports PDM interface (for MEMS MICs). My package has...

Hi,everyone! I want to know if FDCAN ( I'm using STM32H7) has lost the automatic Bus-off Recovery mechanism. Looking Forward to get your reply.Thanks!
UART not working
I have an STM32WB55CGU6 on a custom board with a 32MHz HSE. I'm using low power uart1 with PA2 & PA3 pins. My settings for it are: - baud rate 9600- word length 8 bits- 1 stop bit- parity noneIt won't transmit. Cube doesn't receive it, any terminal ...
ST-LINK/V2 LPUART Connection
I tried to set up a UART connection from my custom board to my PC but encountered some problems and after a bit of probing, it seems that UART TX and UART RX are connected to GND. Do I need to enable UART somewhere for the ST-LINK ? Also why do some ...
SPI slave mode send data after transaction complete
I'm trying to send a fixed length packet in SPI slave mode from the STM32 via DMA. The SPI master may send/recv longer than that fixed length packet. It would be nice if the STM32 just sends 0 one the transactions is complete, but it seems to want to...
